Which step is NOT part of safely securing a Semi-Automatic Pistol?

In the context of safely securing a semi-automatic pistol, the action of checking the ammunition type is not a direct step in the immediate process of securing the firearm. The primary focus should be on ensuring that the firearm is safely unloaded and secured, which is achieved through a series of specific actions.

Removing the magazine is crucial because it eliminates the immediate source of ammunition from the firearm. Locking the slide to the rear further prevents any ammunition from being chambered and provides a visual indication that the gun is no longer loaded. Visually checking the chamber confirms that there is no round currently in the firing chamber, ensuring the firearm is safe to handle and store.

While understanding the type of ammunition is important for safe handling and operation, it does not directly contribute to the immediate task of securing the pistol after use. Rather, it falls more into the broader context of safe firearm practices and ensuring compatibility when preparing to load or handle the pistol. Thus, checking the ammunition type is not an essential step for securely handling or storing a semi-automatic pistol after it has been fired.
